Roger - are you trying to connect that odd angled SB Ford water outlet to the radiator? If so, there are 90* versions available that will make life easier - but I'll be dammed if I recall where mine came from - might be the Ford SVT.

Lowes - look in the irrigation plumbing. I seem to recall some aluminum fittings similar to the PEX (Home Depot locally, for me has a better selection of that kind of 'stuff', but if there isn't one near you.....)
